CENTER PROTOCOL v1.0 (AI-FIRST ARCHITECTURE)
1. SYSTEM DEFINITION
UNDERCOVER.CO.ID operates as a semantic knowledge system, not a content website.
The /center endpoint functions as the System Control Plane, responsible for:
- defining how knowledge is structured
- governing relationships between nodes
- controlling retrieval logic for AI systems
- maintaining authority hierarchy across the graph
It does NOT store content. It defines structure.
2. SYSTEM LAYERS (GLOBAL ARCHITECTURE)
The system is composed of 6 interdependent layers:
2.1 Entity Layer (Atomic Layer)
- Smallest unit of knowledge
- Represents: people, concepts, systems, tools, organizations
- All meaning originates here
2.2 Topic Layer (Cluster Layer)
- Aggregation of related entities
- Forms semantic domains
- Not category-based, but relationship-based grouping
2.3 Query Layer (Intent Layer)
- Represents user intent structures
- Entry points into the graph
- Maps questions → topics → entities
2.4 Evidence Layer (Validation Layer)
- Supports truth validation
- Contains studies, observations, datasets
- Does NOT define meaning, only strengthens it
2.5 Index Layer (Aggregation Layer)
- Structural listing of nodes
- Exists for crawlability and navigation
- Passive system layer (no logic)
2.6 Center Layer (Orchestration Layer)
- Defines system behavior
- Controls interpretation rules
- Governs traversal logic between layers
3. CORE DESIGN PRINCIPLES
3.1 Graph-First Architecture
All content is treated as a node in a graph, not a page in a hierarchy.
Relationships matter more than content volume.
3.2 Entity Dominance Rule
Entities are the root of all semantic meaning.
- Topic = derived from entity relationships
- Query = maps to entities
- Evidence = validates entities
No content exists independently of entities.
3.3 Non-Redundancy Rule
/center must NOT replicate:
- /index pages
- entity lists
- topic catalogs
- query inventories
It only defines structure, not inventory.
3.4 AI Interpretability Rule
All structures must be interpretable as:
- nodes
- edges
- relationships
- traversal rules
No narrative explanations inside system logic layer.
4. RELATIONSHIP MODEL (CORE GRAPH LOGIC)
The system operates on a directed multi-layer graph:
4.1 Primary Relationships
- Entity → Entity (related_to)
- Entity → Topic (belongs_to)
- Topic → Entity (contains)
- Query → Topic (targets)
- Query → Entity (resolves_to)
- Evidence → Entity (validates)
- Evidence → Topic (supports)
- Index → All Layers (aggregates only)
4.2 Relationship Priority Rules
- Entity relationships override topic structure
- Topic relationships override index structure
- Evidence cannot override entity logic
- Query results must resolve to entity nodes
5. RETRIEVAL ENGINE LOGIC
When a query enters the system:
Step 1 — Intent Parsing
Convert query → semantic intent vector
Step 2 — Topic Mapping
Match intent → closest topic clusters
Step 3 — Entity Resolution
Extract highest relevance entity nodes
Step 4 — Evidence Validation
Filter results through supporting evidence
Step 5 — Ranked Output
Return entity-ranked response, not page-ranked response
6. AUTHORITY FORMATION MODEL
Authority is not traffic-based.
Authority is computed via:
- Entity centrality in graph
- Cross-topic connectivity density
- Evidence support weight per entity
- Query coverage depth per entity
- Frequency of entity reuse across clusters
7. SYSTEM HEALTH METRICS
The system tracks structural integrity via:
- Orphan Entity Rate (entities without connections)
- Weak Topic Density (low entity clustering strength)
- Evidence Saturation Index (validation depth per entity)
- Query Coverage Completeness (intent-to-entity mapping gaps)
- Graph Connectivity Score (overall relational density)
8. ENTRYPOINT STRATEGY
Only these are valid public system entry points:
/entity→ atomic knowledge access/topic→ clustered knowledge view/query→ intent-based access layer/evidence→ validation dataset layer/index→ structural aggregation layer/center→ system logic layer (this page)
No other endpoint is considered a primary system entry.
9. SYSTEM BEHAVIOR CONTRACT
The system enforces:
- No isolated content nodes
- No unlinked entities
- No topic without entity support
- No query without resolvable entity output
- No evidence without entity attachment
Everything must resolve into graph structure.
10. FINAL ARCHITECTURAL POSITION
/index= inventory layer (what exists)/center= intelligence layer (how it works)/entity= meaning layer (what things are)/topic= clustering layer (how things group)/query= intent layer (why users come)/evidence= validation layer (why it’s true)
STRUCTURED SUMMARY
The CENTER PROTOCOL defines UNDERCOVER.CO.ID as a graph-based semantic system where /center functions as the orchestration layer controlling relationships, retrieval logic, and authority formation. It does not store or list pages, but governs how entities, topics, queries, evidence, and indexes interact within a structured knowledge graph optimized for AI interpretation and semantic search systems.
